COMBINATION CENTER .AND SIDE DUMP CAR.

Specication of Letters-Patent.

Application led August 6, 1917. Serial No. 184,599.

To aZZ whom t may concer/n Be it known that I, JOHN O1. NEIKIRK, acitizen of the United States, and resident of Lombard, in the county ofDu Page and State 0f Illinois, have invented certain new and usefulImprovements in a Combination Center and Side Dump Car, of which thefollowing is a specification.

This invention relates to dump cars, and

more particularly to combination center and side dump cars.

One of the objects 0f this invention is to facilitate the unloading ofcars.

Another object is to simplify dump cars of the type which may beunloaded by center and side dump action.

Another object is to construct the frame of the car in a manner toeffectively withstand pulling and bufling strains.

Another object is to provide a simple and compactly arranged clump carhaving novel means whereby the load may be dumped centrally or to eitherside and adapted to meet the various requirements for successfulcommercial operation.

These and other objects are accomplished by providing adump car having anovelly constructed body with a movable floor whereby the car may beunloaded, and a door in the Hoor whereby the car also may be unloaded. Y

The invention is illustrated on the accompanying sheets of drawings, inwhich,

. Fig. 1 is a fragmentary side elevation of my dump car;

Fig. 2 is a sectional view showing the general arrangement of thedumping parts, the doors in the Hoor being shown open in their dottedline positions for central dumping;

Fig. 3 is a similar sectional view showing the movable Hoor swung fromits normal position for side dumping, and,

Fig. 4 is a plan view, parts being in sec- 46 tion, showing the frameconstruction and also the stationary dumping guide portions.

The various novel features of my invention will be apparent from thefollowing description and drawings, and will be particularly pointed outin the appended claims.

The frame of this car, which is supported upon suitable trucks, thewheels of which are designated by the reference 10, is constructed toeffectively resist pulling and bufng strains and includes two main sidechannel members 11 and 1.2 which are connected at their ends by crossmembers 13 and 14 to the bolsters 13', and to which are respectivelyconnected the end walls 15 and 16 of the body portion 17 of the car.Secured to the end walls of the body portion 17 are end frame portions18, including transversely extending end sills 19 and 2O which areconnected by longitudinally extending bars 21-22-23 and 24 with lthebolsters. The outer ends of the frame portions 18 are connected to themain body of the car by upwardly and inwardly inclined supportingchannels 25. There is one 'set of these channels at each end of the carand the sets converge upwardly toward each other. This frame structurepresents a stiff combination of parts for effectively resisting pullingand buliing strains.

Secured to the side channel members 11. and 12 are downwardly convergingand curved sides 26 and 27 of a permanent centrally arranged hopper, theend members 28 and 29 0f which are connected to the frame members 13 and14 respectively and converge downwardly toward the center of .the car,said side and end hopper members terminating in a central opening 30 forguiding a centrally dumped load between the tracks. Also secured to eachof the side channels 11 and 12 and to the end walls 15 and 16 of thebody of the car is a sidewardly and downwardly extending guide chute 31for guiding a dumped load to either side of the car.

The side portions 32 and 33 of the body of the car extend vertically andthen converge downwardly toward each other forming a hopper-likestructure over the guide chutes. The Hoor 34 0f the Hat bottom carincludes a door frame structure which is mounted for a swinging movementabout two supports 35 and 36 for dumping the load outwardly to eitherside of the car. The dumping of the load by inclining the iioor orgiving the ioor a pivotal movement is controlled by suitable actuationof the supports 35 and 36 around which chains 37 pass, said chains beingsecured to side portions of the iioor.

As shown in Fig. 3, the floor 34 has been swung about its right handpivotal support 35 to dump the oad outwardly over the Patented Jan. 31,1922.'-

-left hand side guide chute 31 'to' the side of the car. Under theseconditions it will be noted that the support 36 is moved to its outerlimit in the slots 38 formed in the end walls 15 and 16'of the body ofthe car, the other support 35 being at the inner extremity of similarslots 39 formed in the end walls of the body of the car. Likewise theload may be dumped to the right of the car by swinging the floor 34 ofthe car about its left hand pivotal support 36, whereupon the load willpass from the body of the car outwardly over the floor 34 of the car andover the right hand side guide chute 31.

Not only can the load be dumped outwardly to either side of the car, butalso it may be dumped inwardly centrally with respect to the car. Inorder to accomplish this result the floor of the car is provided withoppositely arranged doors 40 and 41 which are hinged at 42 and 43 to apart of the ioor or door frame structure. land are arranged to swingdownwardly to dump the load into the centrally varranged chute whichguides the dumping material between the tracks. The doors 40 and 41 areprovided with brackets 44 and 45 respectively to which are connectedchains 46 which are wound around the centrally arranged shaft 47 carriedby the main center beam of the loor of the car. Normally the doors 40and 41 are held in a horizontal position, but may be moved to the dottedline position shown in Fig. 2 for central dumping by an actuation of theshaft 47.

It will be noted by an inspection of Fig.. 2 that the floor of the car,when in its norma-l position, is retained in such position by the siderods or supports 35 and 36 occupying recesses 49 and 50 formed imthe oorstructure.

By means of this arrangement it is seen that the floor or the door framemay be inclined or swung about either of its p-ivotal supports fordumping outwardly to either side of the car, o-r the load may be dumpedinwardly centrally by permitting the floor to remain in its normalhorizontal position and causing la downward actuation of the doorsindependent of th'e floor or door frame. It will be understood that theHoor and doors are returned to their normal positions by rotating theircorresponding rotatable shafts.

It is evident that there may be various modifications of the inventionherein particularly shown and described, and it is my intention to coverall such modifications which do| not involve a departure from the spirit'and scope of the invention as set forth in the following claims.
